Application filed February 8, 1907. Serial No. 856,304.

tions are to bemade through floors, and its object is to form a tight reliable joint and at the same time to reduce the space occupied by such joint,

It consists in the combination of parts and details of construction which will be more fully explained by reference to the. accompanying drawings, in which I Figure 1 is a sectional view of our jointconnection. Fig 2 is a, similar view showing the testing plate a in position. Fig. 3 is a section through the air vent.

In the connection of closet bowls and the like with discharge pipes, it is customary to fit a brass or other section into the upper end of the cast iron discharge pipewith an oakum and lead packing, and to connect a lead pipe with the brass pipc with what is termed a wipe joint, and this again is connected with. the bot tom of the bowl connection by a flange and bolts securing the bowl to the floor and connecting with the pipes below. This connection makes a long, inconvenient and difiicult one to keep tight.

. It is the object of our invention to make a short, tight and sanitary connection, easily put together and maintained,

In the accompanying drawing A is the cast or other iron escape pipe, having an elbow and upturned end as at 2. Within this upturned end is fitted a screwthreaded nipple 3. We have shown this nipple as being tapered both ways from the center; the upper part being also screw-threaded, and upon this is screwed a short brass tubular section 4 having a floor flange 4 which is connected with the flange 5 of the bowl by bolts 6. 1 The interior angle of this connection 44 has a segmental groove or channel formed around the angle; this groove being shown here as approximately a uadrant in cross-section. Within this groove is fitted a similarly shaped rubber gasket 8, and when the parts are bolted together the fiat sides of the gasket fit into the angle at the bottom of the bowl flange and thus makes a thoroughly tight and sanitary joint. The

whole length of the parts from the elbow of .the pipe A to thailange oi the bowl is exceedingly short, and the connection can be made in cramped placcswwhero the ordinary connection could not be used at all.

Fortcsting purposes I employ a thin sheet netal flange as at a, which fits between the nipple 3 and the brass flange .d and which temporarily closes the passage through the parts so that the proper test may be-a 'plied to insure that the joints and connections are all tight; after this is completed the thin metal sheet may be punched or cut out, leaving the apparatus in proper condition.

9 is an air vent outlet from the pipe A, and this outlet is inclined upwardly, so that any back water from the pipe will readily return to the pipe to be discharged in the direction of the flow of the current Having thus described our invention what we claim and desire'to secure by Letters Patent, is-- 1. In a plumbing joint and fitting the combination with the flanged base of the bowl and a conducting pipe having an upper end terminating below said base, of a threaded nipple fixed in the' upper end of said pipe and extending above the same. and a tubular section threaded into en- 2. In a plumbing joint and fitting, a conducting pipe having an upturned elbow, a nipple screwed into the upturned end of the elbow, a brass flange adapted to be screwed upon the upper end of the ipple, a thin metal plate clamped between the nipple and shoulder of the flange, a segmental groove formedv on the inner end of the flange, a packing gasket fitting said greovefand a bowl having a flange corresponding with the gasket holding flange land secured thereto by bolts. 4 j v In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
